Hi to you both,
I'm no Dr but I have had bowel problems since I was born. about 2 years Ago I was diagnosed with Lazy bowel. This was after constant tiredness. Sleeping every afternoon and then at night. Loosing focus after lunch, tiredness after meals.. years and years of poor bowel function. The problem with laxetives for me was that I don't do well will holding in loose stools, and the bowel does build up a resistance to the effects, So I went with Enema's, 1 / day. I feel so much better, 1/2 an hour on the toot each morning. Don't have any problems with meals or tiredness- unless I skip a day but I feel so much better. Not sure, might be a good option.
I might just also mention that I found lazy bowel had a big impact on my mental health. when i was blocked.. I was very moody and found I was more depressed... not sure if you have found this at all?
